Evolution gene selection

Molecular complexation is a precondition for receptor functions such as substrate selection, substrate transportation, isomeric differentiation, and stereoselective catalysis. Although the investigation of such functions with synthetically derived compounds is a relatively new development in chemistry, they are well known and extensively studied functions in the biological domain. Evolution, gene expression, cell division, DNA replication, protein synthesis, immunological response, hormonal control, ion transportation, and enzymic catalysis are only some of the many examples where molecular complexation is a prerequisite for observing a biological process. 

For the selection of descriptors, GA simulated evolution of a population. Each individual of the population represents a subset of descriptors and is defined by a chromosome of binary values. The chromosome has as many genes as there are possible descriptors (92 for the aromatic group, 119 for non-rigid aliphatic,... 

Tubulins arose very early during the course of evolution of unicellular eukaryotes and provide the machinery for the equipartitioning of chromosomes in mitosis, cell locomotion, and the maintenance of cell shape. The primordial genes that coded for tubulins likely were few in number. As metazoan evolution progressed, natural selection processes conserved multiple and mutant tubulin genes in response to the requirements for differentiated cell types (Sullivan, 1988). 

How could Dawkins have come up with such an extreme and counterintuitive position The source can be found in his analysis of selection. Dawkins (1976) did not introduce the notion of replicators, but he certainly popularized it. Some entities exhibit structures of the sort that deserves to be termed information . Replication is the transmission of this information from one replicator to the next, copies producing copies. In biological evolution, so Dawkins argues, these replicators are genes. He also introduced a second process (environmental interaction) and corresponding entities (vehicles). As Dawkins sees it, the relation between replicators and vehicles is development. Replicators produce the vehicles in which they reside. Vehicles are clumsy robots, totally governed by the replicators that produce them. 

When evolution selects the genes that build the parts of brains (modules) that produce a particular kind of behaviour, and evolution selects them because of the fitness benefits of that kind of behaviour, we have the conditions for a perfect evolutionary psychological explanation.
